Why are there stains on my ceiling near AC vents?

Those annoying water marks around your air vents are caused by condensation. If you have an air conditioner and the air in your attic is warm, condensation will accumulate.

This isn’t an altogether uncommon occurrence for residents of Rockledge, FL, and surrounding areas. But should you be concerned?

When there are water stains near an air vent, the insulation and drywall in that area are at risk.

Here are some of the reasons why water stains are appearing around your AC vents:

Lack of Insulation: An insufficient amount of insulation in the ductwork is a common cause of water stains around air vents.

Leaks Around Vents: Improperly sealed vents or vents with seals that have worn down are a common cause of condensation.

Clogged Air Filter: Stains surrounding your vents may also be caused by clogged air filters. Because the incoming cold air cannot escape the system, condensation forms when the warm air from the blower meets the cold air from the blocked filter.
